' PISTON-RING TESTER.

Application led February 25, 1922. Serial No. 539,070.

for the detection of defects, the' invention' bey ing especially designed for testing the opposite edges of piston packing rings, whereby waves or uneven surfaces may beeasily seen.

Another object of the invention is the provision of a device as above set forth, which is simple in construction' and by means of which tests may be made quickly and with accuracy and precision. y

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

.In the drawings Figure 1 is a top plan view of the invention. Y

Figure 2 is a side elevation of the same. Figure 3 is a vertical central sectional view.

of Figure 2.

Figure 5 is' a .fragmentary view of a portion `or an'imperfectpiston ring. i

Referring in detail to the drawings, wherein like characters of reference denote 30 corresponding parts, the reference character 10 indicates a base of suitable shape and size.y from which rises a sleeve 11, while extending above this sleeve and mounted for rotation is a cylindrical housing 12 which is open at its top. This housing is provided with a reduced downward extension 13 which is received within the upper end of the sleeve and is rotatable therein. Secured to the upper end of the housing 12 as by threads 14 or other suitable connecting means is a disk 15, the latter providing a horizontally disposed table or gauge which will be hereinafter referred to 'as the lower gauge. This gauge is adapted to support a piston ring as shown at .16 in Figures 2 Figure 4 is a section on the line 4-4 and 3 of the drawings. or it may support articles of a diiferent character.

(lo-operating with the lower gauge 15 is an upper gauge 17 which is of a similar construction and is threadedly or otherwise connected to a dome-like cap or adapter 18. This cap is provided with a central opening 19 having an upper restricted endy so as to provide a shoulder 20,`the latter being adaptedto engage a. ball-like extremity 21 provided at one end of a Supporting stud 22. This provides for a free universal connection between the adapter 18 and stud 22 and forms a connection whereby universal movement of the adapter is permitted. The stud 22 extends upward through an opening or slot provided in the end of an arm 23', the said opening extending to the outervend of this arm toV facilitate the insertion and removal of the stud when desired. This arm further provides a handle for the manipulationof the upper gauge 17,` as will be hereinafter apparent.

The inner end of the arm 23 extends from the upper end of a slide which is herein. shown in the form of a sleeve 24 and this sleeve is capable of sliding movement upon a standard 25 which rises from the base 10.

The stud 22'is threaded and has mounted thereon an adjusting nut 26 so that the said stud may be adjusted to permit the gauge 17 to rest freely on the upper edge of the ring 16. o

1 Pivotally connected to the lower-end of the standard 25 as shown at 28 are cams 29, whose arcuate cam surfaces 30 bear against rollers 31 positioned vupon opposite sides ot the sleeve 24, so that when the said cams are moved upon the pivots 28, the saidsleeve will be raised and lowered to raise and lower the upper gauge 17. At one end ofthe i ,arcuate cam surfaces 30 are seats 32, which are engaged by the rollers to yieldinglyhold the sleeve in its elevated position. Extendying from the cams 29 is a yoke-shaped lever 33, the latter embracing the sleeve 11 of the base andbeing provided with a handle or grip 34. c y K By operating the lever 33, the' upper gauge may be elevated and the same moved laterally to one side of the centerof the lower gauge 15, movement in this direction beinglimited by a stop 35 which extends downwardly from an arm 36. This arm is mounted for adjustment rupon the upper end of the standard 25 as shown at 37 and is eX- tended beyond thev opposite side of the standard to support a forwardly and downwardly extending stop 38. The lower end of this stop bears against the'periphery of the lower gauge and when the upper` gauge 17 has its periphery engaged with the" stop, the said gauges will be azrrially aligned and the upper gauge may then be' lowered into the position shown in Figures 2 and 3 of' the drawings. e

Located Withinthe ho-using 12is al source of light, herein shownI inthe form ot' an in-,

f. candescentlamp 39. This-lamp iscarried at the upper end yoi a hollow stem l() through which passes conductor wires 411 for connection lin an electric ,circuit ,a switch l2 being includedin this circuit forcontrolling the light. The hollow stem 40 yis slidable longitudinal-ly through ay bushing 42 f located within the. extension {13 of 'thevfhousingi 12 and extending radially from .opposite sides of andiconnected to this bushing are studs 43.;l These :studs have connected-to `their outemends vpivot screws 441 which pass through, elongated slots 475 provided` in theA yfolrefshaped lever `33, lwhile thestuds 4:3 passlthrough, andv move longitudinally lin openings-lrprovided'inthensleeve 11g- An i 30 of this apron or shield and surrounding the housingis an operatingtring yor wheel 5 1.. In. theusa of the invention, alring placed upon the lower gauge 15 and the up'- per gaugeswunguover above the top. y The freev end of the lever 34k is'then elevated so that theupper gauge,j17"will be lowered and rest freely onthe upper edge ofthe ring 16v as shown in Figure 3. ot the drawingsy the supporting stud/22 being `so adjusted as to befielievedpot the x `weight of the yupper gangen Simultaneous with the lowering v inoveinentgoi the upperr gauge, Ithe lamp 39 will beelevated due to itsj connection with the-lever'33, son that the lamp ,willlikewise occupy the position shown in Figure V3.

looking between the gauges, yany 4waves or defectsin .the opposite edges of `ring Inaybeeasily Vvdeterrriii'ied by ,they-rays, of l' htlsfhining therethrough. By means 'of y -.be..rottod So thatiho; So-id lee .viewed @for its entire ,civrcuinf ference; By pressing downward upon the en wheel 51,; both gauges and p isouter end of the lever 33, the upper gauge will be elevatedV until the rollers 31enter the lseats 32 of the cams 29 and duringthis elevating movement, the lamp 39 will be lowered so asto move itwithin the plane of the uppei'wsurface ot the lower gauge 15. By this arrangement, danger or injury to tho lamp in placing vthe packing rings upon the lower gauge andl in moving the upper gauge into position, is obyiated. y, g
